The purpose i5 nection with various types of tire machines of these weights is to cause the rear end of to apply the tread in an accurate manner. the chute to swing downwardly so as to move This means comprises a support 5 which the forward end out of the Way when not in may be of any shape desired and of such a use. construction as to prevent the same from In the use of the device it is possible with 50 tilting in any way. Projecting from the some types of machines to attach the chute sides of the support are arms 6 and 7, each direct to the machine. Other types of maarm consisting of a strip of metal having a chines require a support similar to the supbearing opening 8 in its upper end, said port 5. The forward end of the chute is bearing openings registering with each extended downwardly to a point just over the top of the crown of the tire carcass which has previouslybeencompleted on the machine and is ready for the tread. The end of the tread is then laid on the top of the crown and the tread drawn from the chute and laid accurately on the tire carcass. In view of the fact that the tread feeds from the chute direct to the top ofthe crown of the tire carcass, there is no possibility of the tread wrinkling.

From the foregoing it Will be readily seen that this invention provides novel means for applying a tread .to .a tire; carcass with little time, labor and expense and with great accuracy, as the laying of the tread does not depend on the skill of the operator. All of these features are possessed by this device which is composed of only a small number of simple parts andwhich may be used in connection with various tire machines.

WVhat is claimed is our signatures.

A device of the character described comprising a stationary support, uprights secured upon opposite sides thereof and extending above the top, a shaft extending through said uprights, a pair of plates journaled upon said shaft, a pair of longitudinally extending trough forming members of angular formation secured intermediate their ends to said'plates, means for adjusting said members toward or from each other, the plates and trough forming memhers being bodily rockable upon the shaft whereby to be disposed in a selected position depending uponthe diameter of the tire carcass being treaded, and counterbalancing weights on one end of the trough forming members for normally urging said end downwardly.
